  • Method of separating and processing catalyst carriers
    Patent number: 7134619
    Abstract: A method of separating and processing a catalyst carrier that is contained in a processing object that includes a catalyst carrier metal cover to which an exhaust gas pipe is still connected, magnetic carrier foil or a ceramic carrier, a surface-enlarging coating film provided on the magnetic carrier foil or the ceramic carrier, and the catalyst carrier containing precious metal. This method includes the steps of: crushing the catalyst carrier and the metal cover to which the exhaust gas pipe is still connected, using a first crusher of a shearing type; breaking the catalyst carrier containing precious metal from the metal cover, using an impact-type pulverizer; and separating the catalyst carrier containing precious metals from the exhaust gas pipe and the metal cover, using a separator.
